or any search engine for that matter. I'm reading about big companies like Microsoft are in a frenzy to purchase other search engines because they either 1) want the technology 2) eliminate them and acquire their market share. Google in particular has remained at the summit of popularity ever since they've debut 5 years ago. Advertisers are flocking to them no doubt and their technology is transferrable to Fortune 500 companies who want to utilize it internally, BUT the burning question is after all that. How can a company who's basically built around a simple idea, to make searches fast and accurate be worth Biillions of dollars !? What are their other revenue streams?
